14 Claims. (Cl. 189-78) The present invention relates to a clip forsecuring a resilient insulating strip in place on the frame section of astorm window.

In the installation of storm windows to prime windows, especially of thetypes fabricated from metal, it is desirable to use an insulating stripbetween the registering metallic sections of the two windows to providea seal excluding air and dirt from the space between the two windows andto insulate against the transfer of heat from the interior to theexterior of the windows through the metallic sections. For efficientresults the insulating strip is fabricated from rubber, plastic, felt orany other suitable insulating resilient material.

It is an object of the present invention to provide a clip for securelyretaining an insulating strip in place on the frame section of ametallic storm window.

It is a further object of the present invention to provide a clip toretain a resilient insulating strip in place on the frame section of astorm window without the necessity of using adhesives, rivets, staplesor other means that may injure the resilient material upon attachment orremoval of the strip from the section.

It is still another object of the present invention to provide a clipthat is easily attached or removed from its position retaining aninsulating strip in place on a storm window.

Other objects and features of the invention will become apparent as thedescription proceeds, especially when taken in conjunction with theaccompanying drawings, wherein:

Figure l is a plan view of a storm window with the clips in place ateach of the corners.

Figure 2 is an enlarged fragmentary view of a corner of the stormwindow.

Figure 3 is an enlarged section taken through the line 3-3, Figure 2.

Figure 4 is a perspective view of the clip.

Figure 5 is a side view of the clip.

Figure 6 is a section on the line 6-6, Figure 5.

Referring now to the drawings, Figure 1 shows a storm window designatedat 10 of the type used with metal prime windows. The window is comprisedof four frame bars 12 of similar cross-section, a pane of glass 14,splines 16 to hold the glass in place, insulating strips 18, and clips20.

Frame bar 12 has a wall 21 provided at its inner edge with an inclinedlip 22 engageable in a recess or seat 23 extending along the associatedspline 16. At its outer edge the wall 21 of the frame bar 12 turnslaterally to form the outer wall 24. At its edge opposite to the wall21, the wall 24 turns inwardly to form the wall 26 and thence laterallyagain to form the wall 28. The metal of the bar extends inwardly fromthe wall 28 and is then reversely bent to form the inwardly extendingdouble thickness wall 30. Walls 28 and 30 constitute a seat for the edgeportions of the glass 14. The reversely bent portion of the frame barcontinues outwardly parallel to and spaced from the wall 26, asindicated at 33, providing a strip holding groove 34. The terminal edgeis reversely tes atent U bent at an acute angle to form the stripretaining flange 36. The bars 12 are joined together with miteredcorners to provide the groove 34 continuous around the periphery of theframe.

The insulating strip 18 is of a resilient'material having a tubularportion 40 that provides a sealing surface and a flange portion 42connected to the tubular portion 46 by a web 43 that extendssubstantially parallel to the tubular portion. The portion 42 has athickened edge 44 forming a lip 45 defining a groove 46 that runslongitudinally along the strip. A strip is provided for each side of theframe with each strip being cut with a mitre at each end. The strips maybe assembled to the bars by sliding them endwise with the flangeportions 42 of the strip entering the groove 34 of the bars and theportion 36 of the frame interlocking in the groove 46 of the strip. Thestrips are cut to a length so that the mitered ends abut each other toform a continuous surface around the periphery of the frame.

To hold the strips 18 securely against each other at the corners andagainst longitudinal displacement the clips 2% are provided. The clip ispreferably fabricated from metal stock and has a flat portion 50including a right angled corner 51, the edge portions of which are bentlaterally at right angles to the plane of the flat portion 5%) toprovide abutment flanges 52. Two ears 54, each coplanar with the portion50 and disposed at right angles to each other, are provided. The outeredges of cars 54 are offset inwardly from the adjacent abutment flanges52. The outer corners of the ears 54 are cut off as indicated at 56 toeliminate sharpcorners. A tab 58 is struck down from each ear to providesharp corners 66 for a purpose to be described. In addition, anembossment 62 is provided to extend from the center of portion 50 in adirection opposite to abutment flanges 52 and tabs 53.

It will be noted that strips 18 include tapered flanges 64 which extendoutwardly beyond the abutment flanges 52 to form a continuous sealingmember.

After the insulating strips 18 have been assembled to the frame bars,the clips 24 are placed in position by forcing the ears 54 and portion54) of the clip diagonally into the space between the flange 42 of thestrip and the wall 26 of the frame bars. The resiliency of the strip 18allows the points 6t) to embed themselves into the material of thestrips and holds the strips against displacement. The embossment 62presses against the wall 26 of the frame bars to provide frictionalresistance against relative movement between the clip and the bar.

The terms inwardly and outwardly as used herein refer to directionsrespectively toward and away from the center of the frame substantiallyin the plane thereof.

The drawings and foregoing specification constitute a description of theclip for storm window insulating strip in such full, clear, concise andexact terms as to enable any person skilled in the art to practice theinvention, the scope of which is indicated by the appended claims.
